JEWEL-PIN SETTER.

Application filed December 20, 1923. Serial No. 681,839.

T0 41 whom it may concern:

Be it known that 1, PAUL EMMETT GALAME, a citizen of the United States,and a resident of Holly Springs, in the county of Marshall and State ofMississippi, have invented a new and useful Improvement in a Jewel-PinSetter, of which the following is a full, clear, and exact description.

My invention relates to improvements in devices for setting jewel pinsin watches, and itconsists in the combinations, constructions andarrangements herein described and claimed.

An object of my invention is to provide a device by means of which ajewel pin may be set accurately and quickly in watch rollers, so thatthe pin is in exact alinement with the longitudinal axis of the roller.

A further object of my invention is to provide a device of the typedescribed, which will hold the pin and which will enable the roller tobe held at right angles thereto, so that the pin may be set perpendicrearly to the surface to which it is secured. with very little trouble.

A. further object of my invention is to provide a tool which will holdthe pin rigidly while it is being secured in position by cementing.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be parti 'ularry pointedout in the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this ap' plication, in which Figure 1 is a top plan view of the tool,

Fig. 2 is a side elevation of the tool,

Fig. 3 is an enlarged view of one end of the tool, and

Fig. t is an enlarged cross-section of one end, showing its applicationin the setting of the jewel.

In carrying out my invention, I provide a shank or body portion 1 whichis made of metal, and which is provided with a handle 2. his shank ispreferably cylindrical, but has a cut-away portion beginning at thepoint 3 in Figs. 1 and 2, and extend ing forwardly to the end of thedevice. At l 1 have shown a stud which is secured to the shank in anysuitable manner. This stud has a slot arranged to receive a grippingfinger 5. The rear end of this finger is pressed on by a leaf-spring 6,which is secured at 7 to the shank, and which bears on the linger in therear of the pivot pin 8. The front part of the gripping finger isnormally held against the fiat surface 9 of the shank 1. twill beobserved that the point of contact is very near the end of the shank,since the under surface of the gripping finger 5 is inclined withrespect to the flat surface, when the tool is not in use.

It will be observed that the shank 1 isprovided with a longitudinal bore10, extending inwardly from the end thereof, and that on the upper flatsurface is a small V shaped groove 11. This groove is for the purpose ofmounting and holding the jewel pm.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. In Fig. 4, T have shown adouble roller 12. In re placing a jewel pin, the roller may be removedfrom the balance staff, or left on the staff, as desired. The brokenpart of the ruby jewel is removed from the hole in the roller, and ajewel pin of the proper size is selected to replace it. This jewel pinis placed in the groove 10 of the shank, so that it projects beyond theend of the tool, and the gripping finger 5 is released so as to grip thejewel 13. The roller is then brought up, and the pin is inserted in thehole in the roller. It will be observed that the end of the shank and ofthe gripping finger 5 form a straight edge at right angles to the axisof the bore 10, so that when the roller is placed on the end, and thepin 13 is inserted in the hole, the pin will be parallel to the axis ofthe roller, and at right angles to the part to which it is to besecured. The pin, of course, is provided with proper cementing material,and the pin and the roller may be held by the tool, which can then bemelted over an alcohol lamp or with an electric heater, to cause thecement to flow around the jewel in the hole in the roller. The tool maybe then removed from the frame, and the cement will cool so as to holdthe jewel in place. In the case of double rollers, the bore 10 allowsthe guard roller to enter therein, so that the jewel may be properlyset.

With this tool, the setting of jewel pins is very readily accomplished,besides resulting in an economy of time 1n setting ewels. It alsoinsures the proper and accurate securing of the jewel in the roller.

It will be noted that the bore 10 is flattened to provide a thinpartition between the bore and the groove 11. As Will be seen from Fig.4, this permits the pin to be s11 ported, While the partition is thinenoug1 to enter between the pin and the hard roller of the smallest ofthe double rollers, such as those used in bracelet Watches.

I claim:

1. A jewel pin setting device, comprising a shank having a longitudinalgroove arranged to receive a jewel, and being provided With an inwardlyextending bore arranged to receive a portion of a Watch roller, and aspring finger carriedby the shank and adapted to hold the pin in thegroove,

the end of the shank and the spring finger constituting a straight edgeat right angles to the axis of the groove.

2. A jewel pin setting device, comprising shank, a handle for the shank,said shank having a central longitudinal bore extending inwardly at oneend, a portion of the shank being flattened, a finger pivotally mountedon said flattened portion, said flattened portion having a longitudinalV- shaped groove arranged to receive and center a j eWel pin, and aspring for normally forcing said finger toward the groove, the end ofsaid shank and said finger being flat tened and in a plane atrightangles to the axis of the groove.
